Telegraf
Telegraf is an agent written in Go for collecting metrics from the system it's
running on, or from other services, and writing them into InfluxDB or other
outputs.
Design goals are to have a minimal memory footprint with a plugin system so
that developers in the community can easily add support for collecting metrics
from well known services (like Hadoop, Postgres, or Redis) and third party
APIs (like Mailchimp, AWS CloudWatch, or Google Analytics).
New input and output plugins are designed to be easy to contribute,
we'll eagerly accept pull
requests and will manage the set of plugins that Telegraf supports.
See the contributing guide for instructions on writing
new plugins.
Installation:
NOTE: Telegraf 0.10.x is not backwards-compatible with previous versions
of telegraf, both in the database layout and the configuration file. 0.2.x
will continue to be supported, see below for download links.
For more details on the differences between Telegraf 0.2.x and 0.10.x, see
the release blog post.
Linux deb and rpm packages:
Latest:
0.2.x:
Package instructions:
- Telegraf binary is installed in
/usr/bin/telegraf
- Telegraf daemon configuration file is in
/etc/telegraf/telegraf.conf
- On sysv systems, the telegraf daemon can be controlled via
service telegraf [action]
- On systemd systems (such as Ubuntu 15+), the telegraf daemon can be
controlled via
systemctl [action] telegraf
Linux tarballs:
Latest:
0.2.x:
tarball instructions:
To install the full directory structure with config file, run:
sudo tar -C / -xvf ./telegraf-v0.10.1-1_linux_amd64.tar.gz
To extract only the binary, run:
tar -zxvf telegraf-v0.10.1-1_linux_amd64.tar.gz --strip-components=3 ./usr/bin/telegraf
OSX via Homebrew:
brew update
brew install telegraf
From Source:
Telegraf manages dependencies via gdm,
which gets installed via the Makefile
if you don't have it already. You also must build with golang version 1.5+.
- Install Go
- Setup your GOPATH

How to use it:
$ telegraf -help
Telegraf, The plugin-driven server agent for collecting and reporting metrics.
Usage:
telegraf <flags>
The flags are:
-config <file> configuration file to load
-test gather metrics once, print them to stdout, and exit
-sample-config print out full sample configuration to stdout
-config-directory directory containing additional *.conf files
-input-filter filter the input plugins to enable, separator is :
-output-filter filter the output plugins to enable, separator is :
-usage print usage for a plugin, ie, 'telegraf -usage mysql'
-debug print metrics as they're generated to stdout
-quiet run in quiet mode
-version print the version to stdout
Examples:
# generate a telegraf config file:
telegraf -sample-config > telegraf.conf
# generate config with only cpu input & influxdb output plugins defined
telegraf -sample-config -input-filter cpu -output-filter influxdb
# run a single telegraf collection, outputing metrics to stdout
telegraf -config telegraf.conf -test
# run telegraf with all plugins defined in config file
telegraf -config telegraf.conf
# run telegraf, enabling the cpu & memory input, and influxdb output plugins
telegraf -config telegraf.conf -input-filter cpu:mem -output-filter influxdb
Configuration
See the configuration guide for a rundown of the more advanced
configuration options.
